FIELD OF THE INVENTION

The present invention relates to a compound having a silsesquioxaneskeleton, a polymer obtained using the compound, and uses of thepolymer.

BACKGROUND OF THE INVENTION

Polyorganosiloxane has excellent heat resistance, weatherability andsurface-modifying function, and therefore it is used for semiconductorinsulating protective films, flame retardants and coating materialadditives. For example, a coating agent prepared by blending an organicpolymer with polyorganosiloxane can provide the surface of a materialcoated with the agent with functions such as water repellency. Therepresentative examples of the organic polymer are acryl resins,polyurethanes and alkid resins. In general, however, these polymers donot have a good compatibility with polyorganosiloxane. Accordingly,there have been the problems that the coating agent is liable to becomecloudy by blending polyorganosiloxane, and that a coating film obtainedfrom the coating agent is liable to be whitened. That is, an additionamount of polyorganosiloxane has been restricted.

It has so far been known that an introduction of a polysiloxanestructure into principal chain and/or side chain of an organic polymermakes it possible to improve the characteristics of the polymer such asheat resistance, water repellency and weatherability. Disclosed in, forexample, the patent document 1 is a process in which apolysiloxane-containing polymer is radically copolymerized with otheraddition-polymerizable monomers to thereby produce a polysiloxane graftcopolymer having a polysiloxane structure in a side chain.Polysilsesquioxane having a structure in which 1.5 oxygen atom is bondedto one silicon atom is disclosed in the patent document 2. It isdescribed in the document that a polysilsesquioxane derivative having apolymerizable unsaturated bond and two or more functional groups such ashydroxyl group and alkoxy group is copolymerized with otheraddition-polymerizable monomers to thereby obtain a vinyl polymer intowhich a siloxane side chain is introduced. All of them are considered tobe excellent in heat resistance, water repellency and weatherability ascompared with the homopolymers of the other addition-polymerizablemonomers.

It has so far been tried to enhance the content of a polyorganosiloxanestructure in an organic polymer for the purpose of improving thecharacteristics as described above. However, in the foregoing organicpolymer having a polyorganosiloxane structure, such a high improvingeffect as expected has not been provided to the characteristics such asheat resistance, water repellency, weatherability and electricinsulating property. Accordingly, strongly desired is apolyorganosiloxane having a structure which further elevatescharacteristics such as heat resistance, water repellency andweatherability in the organic polymer.

Still another object is to provide a coatingagent, a plastic substrate and an optical material each obtained byusing the polymer.

In the tables described above, Q²-1-1 to Q²-89-2 described in the columnof Q² have meanings shown in the following Formula (Q²-1-1) to Formula(Q²-89-2). A code “<” shown at a left end in these formulas shows abonding point to an Si atom.

Comparative Example 1

<Production 1 of Polyamic Acid>

An NMP (45 g) solution of 4,4′-diaminodiphenyl ether (2.39 g) was cooledunder nitrogen atmosphere. Pyromellitic dianhydride (2.61 g) was addedto the above solution while maintaining the temperature of the reactionsystem in a range of 5 to 70° C. Then, the solution was stirred for 20hours to obtain a polyamic acid vanish (50 g) having a polymerconcentration of 10% by weight. Polyamic acid contained in the abovevanish is named PA acid 1.

Example 7

<Production 2 of Polyamic Acid>

A polyamic acid vanish (15 g) having a polymer concentration of 20% byweight was obtained in the same manner as in Comparative Example 1,except that pyromellitic dianhydride was changed to Compound (1-1-4)(1.49 g) and 4,4′-diaminodiphenyl ether was changed to Compound (1-3-7)(1.51 g) and that a use amount of NMP was changed to 12 g. Polyamic acidcontained in the above vanish is named PA acid 2.

Example 8

<Production 3 of Polyamic Acid>

A polyamic acid vanish (15 g) having a polymer concentration of 20% byweight was obtained in the same manner as in Example 7, except thatCompound (1-1-4) was changed to pyromellitic dianhydride (0.39 g) andthat a use amount of Compound (1-3-7) was changed to 2.61 g. Polyamicacid contained in the above vanish is named PA acid 3.

Example 9

<Production 4 of Polyamic Acid>

A polyamic acid vanish (10 g) having a polymer concentration of 30% byweight was obtained in the same manner as in Example 7, except that ause amount of Compound (1-1-4) was changed to 2.63 g and Compound(1-3-7) was changed to 4,4′-diaminodiphenyl ether (0.38 g) and that ause amount of NMP was changed to 7 g. Polyamic acid contained in theabove vanish is named PA acid 4.

Example 10

The respective vanishes of PA acid 1 to PA acid 4 were diluted tosuitable concentrations by butyl cellosolve and coated on a glasssubstrate by means of a spinner. It was pre-baked at 80° C. for about 5minutes and then subjected to heat treatment at 220° C. for 30 minutesand then at 300° C. for 60 minutes to form the respective polyimide thinfilms. These polyimide thin films are designated as PI-1, PI-2, PI-3 andPI-4. PI-1 to PI-4 were measured for physical properties, and theresults thereof are shown in Table 29.

Example 11

<Production of Polyester>

Two drops of titanium triisopropoxide were added to a mixture ofCompound (1-1-2) (3.12 g, 2.25 mmol) and butanediol (0.40 g, 4.44 mmol)under nitrogen atmosphere, and the solution was heated and stirred at220° C. for one hour. After cooling, the content was taken out to obtain1.91 g of a polyester.

Example 12

A part of the polyester obtained in Example 11 was completely dissolvedin NMP (9 g), and this solution was diluted to a suitable concentrationby butyl cellosolve and coated on a glass substrate by means of aspinner. It was pre-dried at 80° C. for about 5 minutes and thensubjected to heat treatment at 100° C. for one hour and then at 220° C.for 3 hours to obtain a polyester thin film PE-1. PE-1 was measured forphysical properties, and the results thereof are shown in Table 29.TABLE 29 PI-1 PI-2 PI-3 PI-4 PE-1 Pencil hardness 3H 2H 2H 2H HBRefractive index >1.710 1.599 1.601 1.556 1.58 Light transmittance (%)49 91.2 87.5 95.8 99.6 Surface free energy 40.4 31.7 31.9 29.8 31.6Thermal 182 375 360 377 366 cracking-starting temperature (° C.) 5%weight-reducing 199 438 460 448 387 temperature (° C.) 10%weight-reducing 231 502 518 496 413 temperature (° C.)

Comparative Example 2

<Production 1 of Epoxy Resin>

Bisphenol A glycidyl ether (brand name: EPICLON 850S, manufactured byDainippon Ink & Chemicals Inc.) (0.3 g) and 4,4′-diaminodiphenyl ether(0.176 g) were dissolved in NMP (1.11 g) to obtain an epoxy compoundsolution having a compound concentration of 30% by weight. This solutionwas coated on a copper foil, pre-baked at 80° C. for about 30 minutesand then subjected to heat treatment at 220° C. for 60 minutes and thenat 220° C. for 60 minutes under reduced pressure, and it was subjectedto etching treatment to obtain an epoxy resin film having a thickness ofabout 40 μm. The above film had an average light transmittance of 65.2%in 400 to 800 nm, and a wavelength in which the light transmittance wasless than 1% was 345 nm.

Example 14

<Production 2 of Epoxy Resin>

An epoxy compound solution having a compound concentration of 30% byweight was obtained in the same manner as in Comparative Example 2,except that EPICLON 850S was changed to Compound (1-1-5) (1.0 g) and ause amount of 4,4′-diaminodiphenyl ether was changed to 0.145 g and thata use amount of NMP was changed to 2.67 g. The above solution wastreated in the same manner as in Comparative Example 2 to obtain anepoxy resin film having a thickness of about 100 μm. This film had anaverage light transmittance of 81.4% in 400 to 800 nm, and a wavelengthin which the light transmittance was less than 1% was 260 nm. That is,it is apparent that a PSQ skeleton can be introduced into the epoxyresin without adding polysiloxane and that the resulting coating film isimproved in transparency as compared with the coating film prepared inComparative Example 2.
